My invention relates to improvements in burners for furnaces 4and the likevvherein a plurality of independent-ly controlled burner units are mounted in separately removable relation Within an- `adjustable burner setting.

TheV primary object of my inventionjis to )rovide an improved fuel burner for furnaces. j 4

nother object is to' provide an' improved 1ol burner consisting of a plurality of separately controlled and independently mounted burner units, said units being separately removable from the burner setting to permit the repair or replacement of any unit Without l interfering with the operation of the remaining units of the burner.

A further obj ect is to provide' an improved device of the character describe'dwherein the burners are accessible from out-sidev of the JV furnace and `in` which repair and' replacement may be made Without-shutting down the furnace. v l, Another object is to provide an improved burner provided with' improved means for admitting and regulating the air supply.

A further object is to provide an improved device having an adjustable setting` adapted to be applied upon furnaces of various types and in connection with the furnace Wallsaoof various constructionsand thicknesses.

Another object' is tol provide .an improvedburner comprising plurality of independent burner units .adapted to be readily removed and applied in connection With vari- 35 ous types and sizes of furnacesl i l throughout the specification and dravvings,l

and in which Fig. 1 is a front ele'vationof my improved fuel burner and setting, parts being' broken away to sli-ovv the'arrangement'of' the'burner units; v

form to variousv thicknesses of 'vvall construction.

Fig. 2 is a vertical section taken upon the line 2-2 of F ig. 1 in the direction indicated, and disclosing the manner in which the burner units may be removed from the setting, and j 3 is avertioal section taken upon the line 33 of Fig. 1 inthe direction indicated, i and disclosed the manner in which the setting' may be extended to conform to -vvalls o'fvar'ious thicknesses.' Y i.

Referring to the drawings, the numeral 1 is used to designate the vvallof a] furnace Within Which is mounted a burnersetting consisting' of a main housing box 2 set Within the" Wall 1 and an adjustable `housing box 6b" l 3 slida'bly telescoping onto the main housing box 2. Thev housing boxes 2 and 3' are made of suitable sheet metal in rectangular form and provided with suitable angles 4: secured WithinV the corners. The adjustable housing box 3 isprefe'rably arranged to slide over thev 'outside ofthe main housing 2 and is arranged tol` be extended' asindic'ated lin dotted; linesV 1n Fig. 3 ofthedrawingsv to con-V Within they housings 2` and'l are mounted a Vplurality of burner units designated` in genj i eral by the" numeral 6, each consisting of a i burner holder 7 provided withal plurality of so vertically spaced burner noZZles' 8 connected upon the holder and communicating With a fuell passage 9 formed therein. nnular rings 11 are formed integrally With the holder 7 in axial alinement With the burner nozzles 8,said rings being connected together at theirpoi'nts of tangency as at'12V and connected to the holder by Webs'lB. The rings 11`are" arranged t'o-` receive induction tubes 14 abuttingagainst inwardly disposed shoulders 16 formed Within therings, said' tubes extending inwardly intol the furnace. The burners 8'eidendaxiallyintothe rings 11; and tubes 14 te proj ecta [flame horizontally therethrough into the furnace,

Theburner units Gare independently cnnectedl to a common supply manifold 16 through control valves -17 connected betweenl nipples v18 and l19 communicatingvtvith the manifold y16 Iand. the lholder passages 9" respectively by means of suitable unions 21 and 22. The valves 17 are provided with operating knobs 23 secured upon the outer ends of stems 24 extending outwardly through angles 26 secured across the front of the housing box 3 whereby each unit can be sepa-k rately controlled from the front of the furnace.

The burner units 6 are supp-orted and aligned by means of clamps 27 clamped upon the nipples 18 and -detachably engagingv extensions 28 formed upon the bottoms of the holders 7. The lowermost rings 11 of the units rest upon tiles 29 placed upon the bottom of the main housing box 2` at the extreme back thereof, the weight of the units being supported upon said tiles. Tiles 31 are removably placed between the top of the main housing box 2 and the uppermost rings 11 of the units 6 to close the space above said units 'and to normally hold the units in operative position. The tiles 31 are preferably provided with handles 32 whereby the tiles may be moved outwardly from the setting. The Space between the rings 11 ofthe units 6 is left open to admit air between the units and around the burner induction tubes to support combustion within the furnace.

Dampers 33 are pivotally mounted across 3Q, the front of the burner setting by means of damper rods 34 carried in suitable bearings 36 secured upon frames 37 hinge-dly mounted upon angles .38 extending across the top of the housing boxY 3, a frame 37 and dampers .33 being mounted at each end of the setting.

" 'The damper rods 34 mounted upon one frame 37 and supporting dampers 33 thereon are connected byfsuitablecouplings 39 to correspon'ding rods supporting similar dampers upon theA adjacent frame 37 whereby the 'dampers upon each of the frames 37 may be operated together by a single damper operating handle 41 connected between levers 42 secured upon the outer ends of the rods 34 at one end of the setting. The space between 'the adjacent ends of the frames 37 is closed by a center d-oor 43 hingedly connected to a panel 44 mounted within the upper portion of saidspace and having an opening 45 there- A through.

The units 6 positioned adjacent the center of the burner are provided with one less burner nozzle 8 and ring 11 than the remaining units, thereby providing a space at the top of the burner setting `within which is 'mounted an oil burner sleeve 46 axially alined within the opening 45 and opening into the furnace.V The sleeve 46 is removably sup-v ported byv tiles 47 and held by removable tiles 48, said sleeve being arranged to admit a suitable oil burner which may be used indepen-dently of the units 6 in event the fuel supply thereto becomes interrupted for any reason.

Theweightof the wall 1 extending over the top of the burner setting is preferably supported vupon suitable beams 49. Openings 51 are formed in the beams and openings 52 are formed in the top of the main housing box 2 whereby air, admitted between said beams through openings 53 formed in the furnace wall, may be circulated between the beams to prevent overheating and sagging thereof and admitted in preheated condition into the furnace.

n In operation the setting and burner units are mounted within the furnace wall as above explained, the setting being adjusted to conform to the thickness of the wall of the furnace. Fuel gas supplied through the manifold 16 is controlled for each burner unit by the valves 17 and the burning fuel is projected into the furnace through the induction tubes 14 in the well known manner. The'dampers 33 are set to regulate the supply of air entering the furnace between the burner units 6 to obtain a proper combustion within the furnace.

In event any of the burner units become inoperative for any reason, the supply of fuel to that particular burner unit is shut o by means of its valve 17. The adjacent damper frame 37 or door 43 is then raise-d upon its j hinges and the inoperative unit disconnected at the union 22. The tile 31 above the unit is moved outwardly from the setting thereby' permitting the unit itself to be raised and moved outwardly from the setting as indicated in 'dotted lines in Fig. 2 of the drawings. In this manner, the inoperative unit may be removed for repair, cleaning7 or replacement without disturbing the normal operation of the remaining burner units 6 and without requiring that the furnace be shut down and cooled to give access to the burners. This permits all the burnersto be maintained at full operative efficiency and greatly facilitates the repair and maintenance of the furnace. y

The independent mounting an-doperation of the units permits Y a desired number of identical units to be assembled to provide a burner of desired size. In event it is desired to utilize the burner in connection with another and different furnace, the independent mounting of the units permits the burner to be readily dismantled and, adapted to the new installation, thereby avoiding unnecessary i. duplication of equipment. j

As the supply of fuel gas for the burner units 6 is frequently interrupted, the oil burner sleeve 46 :permits an oil lburner of any suitable form to be inserted into the furnace t0 burn oil and thereby keep the furnace in operation from a -dierent fuel supply when the main fuel ksupply is shut off, thereby preventing the furnace from being rendered inoperative during such interruptions.

While I have illustrated and described what v I now regard as the preferred construction I claim as new and desire to secure by Letters and larrangeurent ef .u1-y improved fuel hurner,the details of construction an-darrangement are of course subject to modification in numerous YWays without departingy from the spirit of my invention.
